Multi-center, observational, active safety surveillance study in participants aged 6 to 35 months in Korea under routine clinical practices.
This study investigates healthcare workers' attitudes towards co-administering COVID-19 and seasonal influenza vaccines, a method supported globally for its efficiency and potential to lessen healthcare burdens. It explores various factors affecting workers' willingness to accept or decline this approach, ranging from demographic to logistical aspects, and examines the link between vaccine hesitancy and co-administration acceptance, aiming to identify and address hesitancy towards both vaccines
The present study OVX836-006 aims principally to: - Confirm feasibility of the concomitant administration of the vaccines under normal clinical conditions, i.e. as two separate concomitant injections into opposite arms; - Introduce an additional representative brand of Quadrivalent Inactivated Influenza Vaccines ; - Demonstrate the absence of interaction between OVX836 and Quadrivalent Inactivated Influenza Vaccines on the Hemagglutinin response; - Demonstrate the absence of interaction between OVX836 and Quadrivalent Inactivated Influenza Vaccines on the nucleoprotein response; - Evaluate the absolute vaccine efficacy of OVX836 compared to placebo in order to corroborate the efficacy signals previously detected in the OVX836 previous studies; - Evaluate the combined vaccine efficacy of OVX836 + Quadrivalent Inactivated Influenza Vaccines versus OVX836 + placebo, and versus double placebo.
The purpose of this research is to determine if the use of a new device can accurately detect a virus infection.
The elderly population and individuals with chronic diseases are at high risk for influenza and influenza-related pneumonia, and it is emphasized that taking pneumonia and influenza vaccine together is effective in reducing mortality as well as hospitalization rates and costs due to pneumonia, influenza, and congestive heart disease. This study that will be carried out will enable to determine the population-based prevalence of the relevant vaccines in the elderly and to determine the determinants of vaccination with the case group to be determined based on this. The aim of the study is two phases. 1. Determination of the prevalence of seasonal influenza and pneumococcal vaccination in elderly people over the over the age of 65 living in Ankara. 2. Investigation of socioeconomic characteristics and vaccine indecision and some health-related determinants of vaccination through the case group created based on the preliminary study on the prevalence of seasonal influenza and pneumococcal vaccination in the elderly over the age of 65 living in Ankara. The study, which includes cross-sectional prevalence and retrospective case-control stages, is planned to be carried out with individuals over the age of 65 living in Ankara province between November 1 and December 31, 2022.
A random, blind and positive control design was adopted.the investigators will assess the safety and immunogenicity of 2 doses of an quadrivalent influenza vaccine virus subunit in children aged 6 to 35 months. A total of 2,772 subjects in the 6-35 month age group were randomly divided into experimental vaccine 1, experimental vaccine 2 and control vaccine groups at a ratio of 1:1:1, and received the corresponding vaccine respectively. 2 doses in the whole course, 28 days apart. Safety observation: All subjects received 30 minutes of immediate response observation after each dose of vaccine and 0-7 days of systematic active safety observation; After 7 days of vaccination, the incidence of adverse events was observed by combining regular weekly follow-up with subject's voluntary report. Safety observation was conducted for 0-28/30 days after each dose of vaccine. Serious adverse events (SAE) were collected within 6 months after the first dose was administered. Immunogenicity observation: Blood samples were collected before the first dose and 28 days after the full dose for influenza virus HI antibody detection. Observation of immune persistence: Blood samples of 3 and 6 months after immunity were collected for influenza virus HI antibody detection.
VAM00001 is a Phase I/II, randomized, modified double-blind, multi-center study. The purpose of this study is to compare 2 dose levels of Panblok H7 (dose 1 and dose 2 of rHA) with a standard squalene dose of adjuvant MF59 to Panblok H7 (dose 3) unadjuvanted in approximately 700 adult participants in order to select one dose formulation to be used for further clinical development. The randomization ratio will be 3:3:1 for Panblok H7 (dose 1) + MF59, Panblok H7 (dose 2) + MF59, and Panblok H7 (dose 3) unadjuvanted, respectively. Each study group will be stratified into the age groups 18-64 years and ≥ 65 years of age. The study duration for each participant will be approximately 13 months.
The primary goal of this study is to evaluate the safety and reactogenicity of multi-component vaccines mRNA-1045 (Influenza and RSV) and mRNA-1230 (influenza, RSV, and SARS-CoV-2) compared with mRNA-1010 (influenza), mRNA-1345 (RSV), and mRNA-1273.214 (SARS-CoV-2) vaccines in healthy older participants.
There is an obvious need for an affordable and more effective seasonal influenza vaccine. TETRALITE is a novel, inactivated, adjuvanted influenza vaccine combining a low dose of a licensed vaccine with the novel, potent LiteVax Adjuvant. A licensed vaccine (Cohort 1) with a normal dose [15 ug per strain] and no adjuvant will be compared with two TETRALITE study vaccines with 1/5th of the licensed vaccine added with a low (Cohort 2) or high (Cohort 3) dose of LiteVax Adjuvant.
